BRYOZOA FROM NEW ZEALAND.

the avicularium this would be Lepralia delicatula, Manzoni (Bry. 

 foss. Ital. 3a cont. p. 11, pi. iii. fig. 17). 



There are also fossils from Napier, Petane, and Tommy Gully, 

 with shorter cells and large pores arranged in a more or less 

 radiating manner, and in appearance and size much the same 

 as Lepralia striatula, Hincks, which I think cannot be regarded 

 as more than a variety of the present. In a specimen of recent 

 L. striatula sent me by Miss Jelly there are only two or three 

 zooecia with avicularia at the side of the orifice. In none of the 

 fossils do I find any, but it is possible that some cells that are partly 

 broken-down m&y have had such avicularia. A fossil from Waipu- 

 kurau Gorge has rather short cells with but few pores irregularly 

 arranged. Close allies are Lepralia regularis, Rss., L. circumornata, 

 Rss., and L. megalota, Rss., from the Austrian Miocene, and the 

 living L. Pallasiana and L. pertusa, Esp. 



Log. Fossil : Crag, Sudbourne (M.-Ed.) ; C. Crag (B.) ; Zanclean 

 of Calabria (Seguenza). Pliocene: Eametto (Sicily); Gerace, and 

 Tenda del Prado (Calabria) (A. W. W.); Napier (N. Z.), and the 

 short variety from Napier, Petane, Tommy Gully, and Waipukurau. 



50. Lepralia pertusa, Esper. 



Cellepora pertusa, Esper, Pflanz. Cellep. p. 149, pi. x. fig. 2. 



Lepralia pertusa, Busk, B. M. Cat. p. 80, pi. lxxviii. figs. 1 & 3 

 (non 2), pi. lxxix. figs. 1, 2 ; Smitt, Eloridan Bry. p. 55 ; Hincks, 

 Brit. Mar. Polyzoa, p. 305, pi. xliir. figs. 4, 5. 



Lepralia pertusa, var. rotundata, Waters, Ann. & Mag. Nat. Hist, 

 ser. 5, vol. iii. p. 31. 



Log. Living : European seas, Elorida, Australia (?) ; New Zealand 

 (?). Eossil : Muddy Creek ; Waurn Ponds (Austr.) ; Napier (N.Z.). 



51. Lepralia rostrigera, Sin. (PI. VII. fig. 17.) 



Escharella rostrigera, Smitt, Eloridan Bryozoa, p. 57, pi. x. figs. 

 203-205. 



Lepralia rostrigera, Waters, Quart. Journ. Geol. Soc. vol. xli. 

 p. 298. 



The specimen from Napier is larger than the recent Eloridan ex- 

 amples, or the fossil from the River-Murray Cliffs. It is adnate, 

 and the zooecia are divided by raised lines ; the surface is punc- 

 tured and granulated ; the oral aperture is 0*22 millim., with an 

 avicularium at each side of the aperture. There is a raised border 

 round the aperture. 



This is allied to Lepralia ingens, Manzoni (Castrocaro, p. 25). 



Log. Living : Elorida. Eossil : R.-Murray Cliffs (Australia) ; 

 Napier (N. Zeal.). 



52. Lepralia longipora, MacGillivray.

 known Polyzoa," pt. ii., Trans. Roy. Soc. Vict. vol. xix. p. 135 5
